广西4种金花茶苗期生长比较

Comparison of Seeding Growth for 4 Camellia chrysantha Species in Guangxi

对广西4种金花茶苗期进行了生长测量和分析,结果表明,弄岗金花茶的苗高生长分别在7、8和9月中旬,显脉金花茶分别在7和9月中旬,普通金花茶与柠檬黄金花茶都只在9月中旬出现生长高峰;显脉金花茶和弄岗金花茶在6月中旬、普通金花茶在7月中旬、柠檬黄金花茶在8月中旬出现地径生长高峰。方差分析及多重比较结果表明,4种金花茶苗高、地径均存在极显著差异,显脉金花茶和普通金花茶较快,弄岗金花茶次之,柠檬黄金花茶最慢。研究结果将为广西这4种金花茶育苗提供参考。

Seeding growth test was made for 4 Camellia chrysantha species, and the results showed that there were three peaks and earlier time of height growth for Camellia longgangensis within one year, and it was from mid July to mid September; For Camellia euphlebia, there were two height growth peaks, and it was mid July and mid Sep- tember; There were only one peaks of height growth for Camellia chrysantha and limonia, and it was mid Septem- ber. There were one peaks of basal diameter growth for all 4 Camellia chrysantha species, Camellia euphlebia and longgangensis were in mid June, Camellia chrysantha in the mid July, Camellia limonia in the mid Au- gust. Analysis of variance and multiple comparison showed that it had extremely significant differences in the growth height and basal diameter of Camellia euphlebia, chrysantha, longgangensis and limonia.
